BELL.

Application filed September 27'VJ 1923.

Be .it known Vthat I, @Bauens L. Huisman, a citizen of the United CStates', residing at Schenectady, in the county et Schenectady and State ci New York, have invented eertain new and useful Improvements in Bells, of which the following .is a speeilication.

The present invention relates to bells and particularly to bells which are required to be made of bell-inetal in order .to obtain the required quality and duration of tone. As is well-known, bell-nietal is an alloy coniposed of copper and tin. It is a species ot bronze and is peculiarly adapted for bells because ot its hardness and sonorousness.

It is the common practice in nianuilactun ing bells to cast them troni bell-metal and afterward machine them on their outer and inner surfaces to give the desired linish and exact dimensions. This means that the entire bell is made from bell-metal which metal is relatively costly and also that there is considerable linishing to do.

The objectof my invention is to provide an improved bell structure which without sacrificing any of the benelits and advantages of a bell made of bell-metal can at the same time be manufactured at a lower cost.

For a consideration of what I believe to be novel and my invention, attention is directed to the accompanying description and the claims appended thereto.

In the drawing the ligure is a side elevation partly in section o'tl a bell embodying my invention. I

Referring to the drawing, l indicates the bell yoke, 2 the barrel or crown, 3 the sound bow or rim, 4 the elapper or tongue, and 5 the clappei bolt, these being the usual parts ot a bell.

Jiccoiding to my invention I forni the barrel or crown of the bell from a metal less costly than bell metal and attach to suoli barrel or crown a sound bow or rim ot' bell-metal. Preferably I torni the barrel or crown otpressed steel of suitable thickness although it may be 'formed of any other suitable metal. The sound bow or riin which as already stated is -formed from bell-l metal, may be cast directly to the lower edge of the barrel or crown or it may be cast separately and then attached to the barrel oi' crown by suitable means such as by Yfusion o't metal, for example, by brazing or welding. In any event, I prefer to torni the sound bow by cei'itritugal casting so as to Serial No. 665,205.

obtain a dense iinetal as a denser metal iinproves the tone Iand wear-ing qual-ities.

In vthe dinwing, the barrel or crownV is shown as being `formed ot' pressed steel vand ias the sound bow cast directly on its lower edge, such edge vbein-g provided with openings 6 through which metal may flow to firmly fix the sound bow to the barrel.

For attaching the barrel to the yoke I provide a hollow ear or tang 7 on top of the barrelwhich lits into the opening or socket 8 in the yoke. Ear 7 and opening 8 are tapered as shown and for drawing' the ear up into the opening and holding it I provide a tapered sleeve or plug 9 which surrounds bolt o and rests at its lower end on bolt head lO. When the nut on bolt 5 is screwed down bolt 5 draws sleeve 9 up into ear 7 and at the same time draws the ear up into opening S. The ear is thus tight-ly clamped in the yoke. Suitable clearance spaces ll are provided to permit the parts to be drawn together.

By the above-described arrangement I effeet a saving` in the cost of the material for a bell in that a. considerable portion of the bell is formed of a metal cheaper than bellmetal. Also I effect a saving in cost in that the pressed steel barrel or crown requires no machine work for finishing it and may be manufactured in quantities at a low manufacturing cost. The quality of tone of a bell depends not only upon the composition or the metal from which the sound bow is made but also to a considerable extent upon its shape and the proportions between its height'1 width and thickness. By making the barrel or crown ot pressed steel it can be easily accurately dimensi-oned in the firstV instance to give the desired proportions so there is lett only the finishing ol the sound bow' to bring the bell to dimension. A bell made in accordance with my invention I have found to have a tone equal in quality to that et a bell termed entirely et bellmetal, this being due to the fact, I believe, that so tar as the material et the bell is concerned, the quality of the tone is governed almost entirely by the character of the metal in the sound bow.

An application o my invention and one to which it is well adapted is that 4of making bells for railroad locomotives, although it is not limited to this use.

In accordanceY with the provisions of the patent statutes, I have described the princi ph'l o operation of my invention, together with the appa atus which I now Consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention may be carried out by other means sneh comn within the scope of the appended claims.

Yhat I Claim as new and desire to secure by Letters Patent of the United States is l. A bell having its barrel formed of one material and its sound bow of a different material.

2. A, bell having its barrel formed of a :ferrous metal and its sound bow of bellmetal.

8. A bell havin` its crown formed ot pressed steel and its sound bow ot bollmetal.

t. In a bell structure, a voke having an opening, a barrel of pressed metal havin,r an ear which lits into the opening, a sleeve in the ear, a elapper bolt which extends through the sleeve and clamps the ear between the sleeve and the yoke, and a sound bow of bell-metzul attached to Said barrel.

5. In a bell` a crown formed of a ferrous material, and a rim formed of centrifugally east bell-metal.

In witness whereof, have hereunto set my hand this 25th day of September, 1923.
